The invention discloses a high-precision pressure and flow measurement and control instrument which comprises a flow pressure converter, the bottom end of the flow pressure converter is fixedly connected with a first mounting pipe, the bottom end of the first mounting pipe is provided with a second mounting pipe, and the bottom end of the first mounting pipe is fixedly provided with a reinforcingring in a penetrating mode. A mounting sleeve is arranged on the outer side of the joint of the reinforcing ring and the second mounting pipe, a limiting groove is formed in the outer side of the mounting sleeve, an inward mounting groove is formed in the bottom end of the outer side of the second mounting pipe, a spring is arranged at one end in the mounting groove, a limiting column is arrangedat one end of the spring, and one end of the limiting column penetrates through the mounting groove; one end of the limiting column is located in the limiting groove, and the limiting column is clamped with the mounting sleeve through the limiting groove; by additionally arranging the mounting sleeve on the outer side of the joint of the second mounting pipe and the reinforcing ring, under the action of the limiting column and the limiting groove, the self-loosening situation of the mounting sleeve is effectively avoided, and the connecting firmness of the first mounting pipe and the second mounting pipe is further improved.
Description
technical field [0001] The invention belongs to the technical field of measurement and control instruments, in particular to a pressure and flow measurement and control instrument with high precision. Background technique [0002] Flow measurement and control instruments are industrial automation instruments used to measure and control the flow and pressure of fluids such as liquids, gases or steam in pipelines or open channels, and are widely used in petroleum, chemical, metallurgy, electric power and light industry industries. In the existing measurement and control instruments, the installation sleeve lacks a limit, and the installation sleeve is easy to rotate under the action of external force, thereby reducing the problem of the connection between the first installation pipe and the second installation pipe. Therefore, we propose a high-precision Pressure and flow measurement and control instruments. Contents of the invention [0003] The purpose of the present inve...
